Adding multiple states in state machine

Question

Hi all,
I have a state machine with many states.  I am using an enum to select state.  I didn't add all the state in the enum at the beginning, so I am adding more statess to the enum and to the state machine as I go.  I found the following pretty troublesome.
If after I made the first 3 state, and I realized that that next 3 states are very similar to the first 3 states.  I want to copy duplicate the first 3 case all at once, instead of duplicating one case at a time.
If I duplicate one state, and the wrong enum is assigned to the state, is there a quick way to change it? 
Are their anything out there that would help plan and keep track of the state machine?
Let me know if you have any cool tips to speed up state machine development, especially topic on enum and case structure (adding, deleting, multiple copy, etc).
Yik

If at all possible, never copy and paste code that is very similar to another piece of code! Try to write modular code. If there are several states that are almost identical except for a few slight differences, wrap those differences in a small case structure within the case.
If you ever find yourself tempted to copy and paste a diagram of code that is larger than a POSTAGE STAMP, reconsider!
